📤 Request
The Request structure in Gofiber's HTTP client represents an HTTP request. It encapsulates all the necessary information required to send a request to a server. This includes:
- URL: The URL to which the request is sent.
- Method: The HTTP method used (GET, POST, PUT, DELETE, etc.).
- Headers: HTTP headers that provide additional information about the request or the needed responses.
- Body: The data sent with the request, typically used with POST and PUT methods.
- Query Parameters: Parameters that are appended to the URL, used to modify the request or to provide additional information.
This structure is designed to be flexible and efficient, allowing users to easily construct and modify HTTP requests according to their needs.
